Rose plant

ABSTRACT

1. A new and distinct cultivar of rose plant of the floribunda class, substantially as herein shown and described, characterized particularly as to novelty by the unique combination of a bushy, heavily branched plant, high greenhouse production of buds of a clear Buttercup Yellow (W), whose shape is oval but with a blunt or flat tip; Spinach Green (W) glossy foliage and a strong fragrance.

This invention relates to a new and distinct cultivar of rose plant ofthe floribunda class, originated by me by crossing the cultivar Mabella,with pollen from the cultivar Minigold.

The primary objective of this breeding was to produce a new and improvedcultivar of the floribunda class bearing pure, clear yellow buds andblooms on plants especially suitable for production of cut flowers ingreenhouses.

This objective was fully achieved along with other desirable traits asevidenced by the following unique combination of characteristics whichare outstanding in the new cultivar and which distinguish it from itsparents as well as from all other cultivars of which I am aware:

1. A bushy, compact plant, making numerous new branches, or canes, fromthe base of the plant.

2. A habit of growth similar to the cultivar Mercedes, U.S. Plant Pat.No. 3,724.

3. A long, oval bud form with a blunt or flat tip.

4. Very, stiff petals which are near Buttercup Yellow.

5. A high centered open flower of approximately 35-40 flowers.

6. A strong, pleasant fragrance.

7. Glossy, Spinach Green foliage.

Asexual reproduction of this new cultivar by budding as performed atElmshorn, Holstein, W. Germany and near Irvine, Calif., shows that theaforementioned characteristics come true to form, and are establishedand are transmitted through succeeding propagations.

The accompanying illustration shows typical specimens of the vegetativegrowth and flowers of this new cultivar in different stages ofdevelopment and as depicted in color as nearly true as it is reasonablypossible to make the same in a color illustration of this character.
